Uploads: After an image is uploaded and PHP times out or runs out of memory during post-processing (the server response is HTTP 500 error), try to resize it three more times. Then, if all attempts fail, do a cleanup of any sub-sizes that may have been created and show an error message asking the user to scale the image and upload it again.
